DEGUSSIT® Ruby® Stones and Files

For Use on Hardened Steel & Carbide Degussit Ruby Stones and Files are made from pure, sintered crystals of synthetic ruby. No bonding material is used, so these stones and files are extremely hard and resistant to changes in shape. This is particularly important for quality precision grinding and finishing. In addition, since Degussit Ruby Stones and Files feature outstanding resistance to wear, they are more economical to use than other comparable tools. Use dry or with Gesswein Stoning Oil to grind, touch up or debur steel and carbide parts. Dress to a fine point to polish highly detailed areas on dies. Excellent for deburring ejector pin holes. Ideal for blending a surface where a straight edge meets a radius. Often used for fine polishing of surgical stainless steel medical instruments. Also recommended for use on materials such as glass, quartz and porcelain.
